Abstract
The utility model discloses an automatic air exhaust grease gun. The automatic air exhaust grease gun comprises a piston with a handle, wherein the piston is arranged in an oil cylinder. The automatic air exhaust grease gun is characterized in that an oil channel is formed above the oil cylinder; the inner diameter of the oil channel is greater than that of the oil cylinder; a one-way valve is arranged between the oil channel and the oil cylinder; and the side face of the oil channel is connected with a grease gunpoint. The automatic air exhaust grease gun has the advantages that the one-way valve which controls grease to be sprayed out is tightly pressed against the oil cylinder and the piston, so the internal sealing performance of the oil cylinder is ensured; and even if air exists in an oil storage room, the air can be exhausted from the grease gunpoint by motion of the piston and cannot be reserved in the oil channel above the oil cylinder, the vacuum absorption force of the oil cylinder cannot be influenced, the phenomenon that the grease cannot be squeezed is avoided, the structure of a connecting position of the oil channel and the oil cylinder is improved, and the automatic air exhaust grease gun can be conveniently manufactured and processed. Compared with the prior art, the automatic air exhaust grease gun has the advantages of good using effect and simple structure and can automatically exhaust the air. According to test which is performed by the applicant, the phenomenon that the air cannot be exhausted is avoided.
Description
Technical field
The utility model relates to a kind of automatic air-discharging grease gun, particularly a kind of automatic air-discharging grease gun that adds butter to automobile and machinery.
Background technique
In the prior art, be used for adding to automobile or machinery the grease gun of butter, its structure generally includes an accumulator, piston with spring is installed in the accumulator, be used for the butter in the extruding accumulator, handle also is installed in accumulator, after the butter in the accumulator uses, piston can be retracted the bottom, the butter of again packing into.Accumulator connects oil cylinder by filler opening, and the piston of connecting handle is installed in the oil cylinder, is used for the butter in the accumulator is extracted out, connects the butter muzzle in the oil cylinder side, piston with butter suction oil cylinder after, advance again the butter muzzle.Seal in order to make in the oil cylinder, the one-way valve of present grease gun is installed in the butter muzzle, and the butter muzzle is connected with oil cylinder one section will leave the space, if there is air to enter, grease gun just can't be worked, and only way is opened accumulator exactly, carry out air-discharging, both wasted the time like this, spilt easily again butter, used pretty troublesome.The claimant has designed a kind of automatic air-discharging grease gun in order to solve the problems of the technologies described above, and has applied for utility model patent, but this technological scheme exists the problem of making processing difficulties.
Summary of the invention
The purpose of this utility model is, a kind of automatic air-discharging grease gun is provided.After air enters piston, can be by pressing handle automatically with Bas Discharged, easy to use, the making easy processing is to overcome the deficiencies in the prior art.
The technical solution of the utility model.Automatic air-discharging grease gun, it comprises the piston with handle, and piston is installed in the oil cylinder, is provided with oil duct above oil cylinder, and the internal diameter of oil duct is equipped with one-way valve greater than the internal diameter of oil cylinder between oil duct and oil cylinder, and the oil duct side connects the butter muzzle.
Above-mentioned automatic air-discharging grease gun, the structure of one-way valve comprises the spring that spheroid is connected with spheroid.
Above-mentioned automatic air-discharging grease gun, oil cylinder connects accumulator by filler opening, is provided with piston and handle with spring in the accumulator.
The internal diameter of oil duct is more than 1.25 times of internal diameter of oil cylinder.
Owing to adopted technique scheme, compared with prior art, oil cylinder is close to by the one-way valve of the utility model control butter ejection and piston is installed, and has guaranteed in-oil cylinder sealing, even air is arranged in the accumulator, also can pass through piston movement, air is extruded from the butter muzzle, and can not stay in the oil duct above the oil cylinder, affect the pull of vacuum of oil cylinder, cause butter to extrude, and improved the structure of oil duct and oil cylinder link position, made things convenient for it to make processing.Compared with the prior art, the utlity model has automatic air exhausting, using effect is good, and advantage simple in structure, through the applicant's test, the phenomenon that air can't be discharged do not occur.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model.Automatic air-discharging grease gun, its structure comprises the piston 1 with handle, piston 1 is installed in the oil cylinder 2, oil duct 3 is arranged above oil cylinder 2, the internal diameter of oil duct 3 is greater than the internal diameter of oil cylinder 2, the internal diameter of oil duct 3 is 1.25 times of internal diameter of oil cylinder 2, between oil duct 3 and oil cylinder 2, one-way valve 4 is installed, one-way valve 4 is comprised of with the spring 7 that is connected with spheroid 6 spheroid 6, elastic force by spring 7, spheroid 6 is blocked the oil outlet between oil cylinder 2 and the oil duct 3, connects butter muzzle 5 in oil duct 3 sides, and butter muzzle 5 is connected to the rifle mouth.Oil cylinder 2 connects accumulator 9 by filler opening 8, be useful on the piston 11 that promotes butter in the accumulator 9, piston 11 linking springs 10 also are equipped with handle 12 in accumulator 9, after using, the butter in the accumulator 9 piston 11 can be retracted the bottom, the butter of again packing into.
Because the spheroid 6 of one-way valve 4 is close to oil cylinder 2, guaranteed the sealing in the oil cylinder 2, when the butter in the accumulator contains air, pulling piston 1, oil cylinder 2 is communicated with filler opening 8, air enters oil cylinder 2 through filler opening 8, and pushing piston 1 is with one-way valve 4 positions of air pressure to oil cylinder 2, the air of compression backs down spheroid 6, discharge by oil duct 3, butter muzzle 5, the push-and-pull piston 1 repeatedly, just can be with the air exhausting in the butter except clean.
If one-way valve 4 is installed in the position of butter muzzle 5, air will be stayed in the oil duct 3, can't get rid of clean.
